You can use Eliminate Polygon Part
Or Multipart to Singlepart and delete or definition query out the smaller islands.
Yes you can use eliminate or multi to single part but smaller polygons within a land mass with also be removed. You used to be able to do this quickly in ArcInfo with adjacency something like reselect smaller than 10sq.km and left or right side poly# equal to ocean or 0 in the case of gadm, syntax is not correct.
How one does this in the ''more sophisticated' ArcGIS I do not know. Anyone know?
